SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 265,114, dated September 26, 1882,

Application filed September 12, 1881. (No model.) 1

To all whom it may concern Be it known that I, MELVIN N. LOVELL, a citizen of the United States, residing at Erie, Erie count-y, Pennsylvania, have invented a 5 new and useful Improvement in Spring Bed- Bottoms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings and the letters or figures of reference marked thereon.

My invention relates to bed-bottoms which are adapted to be folded, and is more particularl y an improvement on the. device shown in Patent to Fowler, N 0. 162,639, April 27, 1875.

Referring to the drawings, Figure lrepresents a plan view of a fragment of the bed-bottom, showing the longitudinal bars A, crosshars B, and springs 0; Fig. 2, an end view of the bed-bottom when rolled up.

' 2o Aside from the construction of crossbars B,

the parts may be the same as in the patent referred to, and therefore need no description from me.

The bars B are made of strap-iron. Each 2 5 section is bent or twisted so as to form a seat for the longitudinal slats and bring its ends,

which are pivoted to the adjoining section, into a vertical position, so that the joint may be made by a single rivet. By this construction the strap-iron forming the cross-stays lies horizontally at the point where they are attached to the longitudinal slats and vertically at the point where they are pivoted together. The vertical parts consist of a quarter-twist on each side of the slat-seat, the twist on one side being right-handed and on the other left-handed, thus making thematerial rise on each side of the slat-seat, as at b, and form a shoulder on each side of slatA sutlicient to prevent the slat moving on its attaching-rivet when the 40 bed receives an oblique strain, as is oiten the case when being rolled-up.

I am aware that it is common to pivot metalbars together at points which are bent at right angles to other points in the bars. I there- 4 5 fore do not claim such a construction as new;

but

What I do claim as new is- Ina spring bed-bottom constructed to be rolled up, a jointed cross-stay formed of sections of strap-iron, which are bent at each end from a horizontal toa vertical plane by a righthand turn at one and a left-hand turn at the other end, and having a horizontal slat-seatin the middle, with shoulders on each side formed by the upturned edges of the bar.

In testimony that I claim the foregoing I have hereunto set my hand this 23d day of August, 1881.

MELVIN N. LOVELL.
